Title: Liquid-crystal display cell
Inventor: SCHADT MARTIN DR
IPC: C09K19/60
Filed: 1979-02-08
Abstract: The electrooptic liquid-crystal display cell has a liquid crystal (4) which is situated between two plates (1) and electrodes (2) and in which dichroic dye molecules (5, 6) are embedded. The embedded dye defines two or more absorption maxima for different wavelengths in the visible region. At least one absorption maximum is characterised by the preferred absorption of light which is linearly polarised parallel to the longitudinal axis of the dye molecules, and at least one further maximum is characterised by the preferred absorption of light which is linearly polarised perpendicular to the longitudinal axis of the molecule. This liquid-crystal display, which is based on the so-called guest/host effect, is especially suitable for multicolored representation of characters and images. <IMAGE>

Title: Frequency synthesiser with mixers and phase-synchronised oscillators - multiplies and filters frequency of prodn. from mixer of selected outputs from externally coded switching circuit
Inventor: FOGNINI BRUNO
IPC: H03B21/02
Filed: 1986-05-21
Abstract: A switching circuit (UE) is supplid supplied with four inputs (S1-S4) whose frequencies are of relatively high consistancy, and produces three outputs (Sx,Sy,Sz) at an arbitrarily lower frequency. The four input oscillators (01-04) are rigidly synchronised in phase by a central clock (TZ) and selected by application of an external code signal (Sc) to  the switching circuit (UE). One output (Sx) passes through a frequency multiplier (V1) and band-pass filter (F1) before being mixed (M1) with another output (Sy). The third output (Sz) is mixed (MF) with an auxiliary signal (SU) which is also synchronised in phase with the nputs inputs. The multipliers (V1,V2) are without any phase ambiguity. ADVANTAGES - Output frequenices can be produced with a relative width greater than the relative bandwidth of the inputs. The phase coherence of the output is maintained during frequency-switching.

Title: Discharge sluice on a continuous-flow washing machine
Inventor: SCHMIEDEHAUS JUERGEN
IPC: D06F31/00
Filed: 1983-06-29
Abstract: The discharge sluice is designed only for the flow-off of spent or excess washing liquor or of rinsing water in continuous-flow washing machines. A sluice wall (21, 22, 23) consisting of a non-perforated outer ring (A) and of a perforated central region (B) is set up in front of the respective partition wall (9, 10, 11) ahead of the end of the counterflow. The level height (C, D, E) is determined, in these chambers (K2, K4, K8), by the width of the ring (A), since the liquid can escape only in the perforated region (B). The distance between the sluice wall (21, 22, 23) and the partition wall (9, 10, 11) is of the order of 2-3 cm. The wall of the drum (1) is perforated at three points (30), in order to discharge the liquid outwards. It is therefore impossible to set a false level. For the individual washing operations, the level is set permanently by the manufacturer and can be selected in an optimum manner in conjunction with the control. <IMAGE>

Patent CH-653446-A5 (CH)
Inventor: CANZEK LUDVIK DR
IPC: G02B17/08
Filed: 1980-10-17
Abstract: This invention provides a high speed catadioptric objective system of F/1.2. The lens system comprises, in accordance with the advance of the light rays, a front or first single lens, a main mirror lens, a counter mirror and a field lens system. The counter mirror is mounted in front of the front lens in order to achieve a short overall length and a good correction of sphero-chromatic aberration. The counter mirror may serve as a focussing element or it may be fixedly mounted to the front lens. The present lens system is distinguished over similar prior art systems by its overall length, which has been reduced by 30 percent, sunshade included. The same type of glass is used for almost all lenses of five preferred embodiments in order to eliminate the secondary spectrum and to enable the objective to be used within a very broad spectral range. An almost perfect correction of aberrations has been achieved with only spherical element faces, thus the systems are suitable when maximum image quality and speed are required. They are useful also for low light level and IR spectral range applications.

Title: Turbogenerator with variable inertia
Inventor: EZBAN MORRIS JACK
IPC: H02K7/18
Filed: 1977-09-09
Abstract: The turbogenerator consists of a turbine (1) linked by a shaft (2) to a generator (3). The inertia of the unit of the rotating mass of the turbogenerator is composed of a constant part, consisting of the mass of the turbine and of the generator, and of another variable part, represented by the mass (4) of variable inertia. When there is a variation of the speed of the turbogenerator, the inertia of the mass (4) varies automatically so as to maintain the normal speed of the turbogenerator. Thus, dangerous speed adjustment manoeuvres are avoided and the maximum efficiency of the turbine is always obtained whilst reducing the weight and consequently the cost of the installation. <IMAGE>

IPC: H02M7/162
Filed: 1977-12-23
Abstract: In symmetric, half-controlled converter bridges for controlling the angle of current flow of periodic alternating voltages applied to the alternating-voltage inputs (1) of the bridge, two thyristors (6, 7) are connected in series with in each case one rectifier diode (8, 9) and in parallel with one another. For protection against unwanted switching of the circuit, a separate freewheeling diode (14 and, respectively 15) is provided in parallel with the series circuit of a thyristor (6 or, respectively 7) with a rectifier diode (8 or, respectively 9) of a bridge branch (4 or, respectively 5). Due to the nonuniform current distribution between bridge (4, 5) and freewheeling branch (14 and, respectively 15), this arrangement entails problems of differences in the dimensioning of rectifier diodes (8, 9, 14 and 15) and thyristors (6, 7) and associated heat sinks. To solve these problems and, in particular, to achieve an equal thermal loading of the heat sinks, it is provided that a freewheeling diode (14, 15) is connected in parallel with each of the two bridge branches (4, 5) in this manner and each of the freewheeling diodes (14, 15) is arranged on a common heat sink with one of the two rectifier diodes (8, 9). The symmetric half-controlled converter bridge is used for regulating drives of electric motors. <IMAGE>

Title: Continuous extraction of oil from olives
IPC: C11B1/06
Filed: 1969-11-17
Granted: 1971-03-19
Abstract: Existing apparatus is utilised in a new manner in the continuous extraction of the oil from olives; as by-products, the complete olive stones are obtained on the one hand and the pulp, from which the oil has been removed and which is free from pieces of stone, on the other hand; it cna thus be used as a cattle feed. The olives are first stoned in a continuous apparatus which cuts up the fruit and separates the complete stones from the flesh which leaves the machine as a crushed paste. After sieving complete stones are added to the paste which is then passed through a continuous press; a good oil extraction results and the stopping up of the perforations of the cage of the press by small fragments of stone is prevented.
